"We didn't really feed into their transition and didn't really give them any chance to get anything going off the rush or the end zone," McDavid said. "Anything that we did give up, (Talbot) was amazing."

McDavid said his goal was just the result of "a lucky bounce."

Canada won its 26th title -- one short of the combined Soviet and Russian record -- and is the first team to retain the championship since Russia in 2009.

Canadian captain Corey Perry becomes the 27th member of the "triple gold club," players who have won the world championship, Olympic gold medal and Stanley Cup. He is the 10th Canadian. At age 19, McDavid is the youngest player to win the world championship, world juniors and under-18 worlds.

After having lost 4-0 to Finland in the preliminary round, Canada was resolved to reduce its turnovers in the rematch with the Finns.

"We used our speed more, we came up with numbers, we made sure we got it deep and we played them in the O-zone," Duchene said. "You get that one (goal) early and make them play from behind, it's a different game."

The Canadians controlled the puck well, shutting down creative forwards such as 18-year-old Patrik Laine, who was named tournament MVP with seven goals and five assists.

"That kid is gonna be great, great future, that's for sure," Finland coach Kari Jalonen said. "I think he grew up in these 2 1/2 weeks a lot as a player. He proved that he can play at this level already at that age."

The result was a lopsided shooting statistic, with Canada racking up 33 shots against 16 for the Finns, whose goaltender Koskinen was a strong presence to stop Canada extending its lead.

"Right now, it's just a disappointment," Finnish forward Jussi Jokinen said. "We played probably one of our worst games of the tournament and they played great," Jokinen said. "We weren't able to create much."

Ahead of the final, Russia was in full control of the bronze-medal game, taking a 4-0 lead in the second period before cruising to a 7-2 win.

Artemi Panarin, who finished with a goal and two assists, said Russia had played with more freedom after a weight of expectation was lifted following its semifinal defeat to Finland on Saturday.

"I think we just relaxed today," said Calder Trophy finalist Panarin. "Until now ... the pressure was serious."

Russian forward Sergei Mozyakin scored two goals, with captain Pavel Datsyuk registering three assists. The U.S. led 30-29 in shots, but Russian goaltender Sergei Bobrovsky produced some impressive saves to protect the lead.
